The core of our technology is our proprietary programmable integrated circuit board, the PowerLine™ Power Management Unit.   PowerLine™ is the centerpiece of our solar management approach, and provides the foundation for our exclusive customized solar lighting products.  Utilizing PowerLine™, we are able to optimally design our solar-powered systems by minimizing sunlight and input requirements by:

• Minimizing PV Panel footprint
• Optimizing number and size of batteries
• Maximizing solar utilization
• Maximizing LED brightness and runtime
• Delivering available energy during low or no-sunlight periods
• Extending product lifecycle and sustainability

PowerLine™ Specifications:
